CRAI with jacks on a 9 high flop

[Xuan768]

I have cake, which has no hand converter, but I'll do my best to describe the hand.

This is one of my first rounds of hands(400 NL), so I have no reads on any of the players.

UTG: 400
Button: 398.25
SB(hero): 405.70
BB: 1343.20

Preflop:
UTG folds.
Button raises to 14.
Hero raises to 35.
Button calls.

Flop (Pot: 74)
2h 9d 3h
Hero bets 55.
Button bets 363.25 and is all in.

Hero ??
